"We have to be a role model for these little girls because who do they have? All they have, literally, is the Kardashians," she said. "And is that a great message for little girls? A whole family of women that take the faces they were born with as a light suggestion? Is that great? No."

Amy then went on to take a dig at Khloe's recent weight loss.

"We used to have Khloe. Khloe was ours, right? Whenever there's a group of women, you identify with one of them," she said. "Khloe, she lost half her body weight -- she lost a Kendall. We have nothing, and I want good role models!"

It's no secret that Khloe has been on a serious workout kick over the last year, and in late July, the 31-year-old revealed that she had lost 35 pounds through diet and exercise.

"I don't really weigh myself, but over time, and I'm not crazy about it. It's like, I know how I want to feel in clothes and it does become addicting once you start losing weight and seeing results. You're like, 'I wanna see more,'" she told Australian radio show NOVA FM.
